## Create a new NetCDF dataset and define two dimensions nc <- create.nc("file.inq.nc") dim.def.nc(nc, "station", 5) dim.def.nc(nc, "time", unlim=TRUE) ## Create two variables, one as coordinate variable var.def.nc(nc, "time", "NC_INT", "time") var.def.nc(nc, "temperature", "NC_DOUBLE", c(0,1)) ## Put some attributes att.put.nc(nc, "temperature", "missing_value", "NC_DOUBLE", -99999.9) att.put.nc(nc, "temperature", "long_name", "NC_CHAR", "air temperature") att.put.nc(nc, "NC_GLOBAL", "title", "NC_CHAR", "Data from Foo") att.put.nc(nc, "NC_GLOBAL", "history", "NC_CHAR", paste("Created on", date())) ## Inquire about the dataset file.inq.nc(nc) close.nc(nc)
